Additional meeting and call-related features and issues within Microsoft Teams for business
Dear Scott,
As a forum moderator, I genuinely wish I could directly review your tenant's calling setup or call logs to diagnose and fix this for you. Unfortunately, my role here is limited to providing general guidance and solutions that can be applied by users. At the time of checking, I didn't find a confirmed widespread Teams calling outage. However, there is a issue where users experience intermittent call failures for Direct Routing calls in the Teams app on iOS. If this matches your setup, the engineering team is aware of it and working on a fix.
If your setup doesn't match the one described above, I recommend that the Global Admin in your organization create a service request with Microsoft Support. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
For additional assistance, use this link to find the appropriate contact number from your region: Contact Microsoft customer support | Microsoft Support
I truly hope you get your issue resolved swiftly. Please know that even though I can't directly intervene, directing you to the correct, specialized support is the most effective help I can provide from my position. Thank you for your patience and understanding. Please let me know if you need anything else. Wishing you all the best.
